This invention'relates toimprovements in thedetails of meat slicing machines.

The particular' objectof the invention is vtoprovide animproved intermitt ntly feeding means for advancing the meat vpast the Islicing` knife.

More specifically, the object of the invention is toV improve the construction of the supporting means for a lead screw such as shown in Patent No. 1,626,902, to G. R. Wood.

Furtherand other objects and advantages vvill be hereinafter set forth in the acc'oiny ing crank and the knife. The main shaft is operated by the fly-Wheel 11 carrying the hand grip 12. Suitable gearing from the main shaftrotates a gear 13 which Vhas a belt connection With the rotary slicingl knife .Y

14. Linkage 15v driven by thevmain` shaft is `connected to the main carriage 1,6y forrecip- Cil ` thickness.

Vrocating the carriagey along guide rails 17 and 18. During the travel of the main carriage towards the knife, the meat clamped thereon is cut in a slice of predetermined The meat is clamped on a meat table 19 by means of an adjustable clamp 20.

Themeat table is guidedfor slidable move- -lead screw 25 With which is engaged a 'halfment on flanges or rails 21 integral with the main carriage. Aftera slice is out .from the,

meatclainped on themeat table. the latter is advanced a predetermined amount towards the planeof` th'enknife.` thereby presenting another thickness-of meat tobe cut off. n

Themeat tableis advanced by meansof a nut 26 yieldinglyurgedr by spring '-27 into enf gagement. Withthe screvv. The'nutlhas an" extension 28 Which is connected to themeat 3 is a section on line 3 3V of Fig. 2;`

table. y The screvv is rotated during the travel of themain carriage by means of a pinion 29 thereon meshing With rack 80 driven from erenc'eiinay be had tov Patent No. 1,626,902,

previously mentioned. 1

It has been found in the construction pre-rv viously employed that there Was a tendency for the Worm 25 to creep during the 'cutting operation'if the meat oferedconsi'derable re-` -sistance during thefcutting operation, 'or if themachin'e was `mounted on an unsteady supportforf if the machine received a sudden blow during itsoperation.

The'means hereina'fter'set forth are effecbycutting off a-sector fromk the body of they wvorm shaft. The. cut awayr end ofthe shaft projects into la circular sleeve' 'zrotlatably 'mounted-in the bearing bracket 37 fast tothe main carriage 16. The outer end of the sleeve Vdhas' a slot engaging a lug 38 in a screWBQ threaded intol the bracket and'locked by a nut 40. Sleeve 36 is formed with a flange 41 abuttingthe inner end ofthe bracket and in tiveto prevent creepingof the Wormshaft Adue to accidental circumstances7 such as those v -me'ntioned above.- jThe right hand end ofthe' YWorml is providedwith a fiat face 35 formed friotional engagement with a circular' disk 42 j abutting theffiat Wall formed on the end of.l the' *screw shaft vat the point vWhere the 'flat facegfi commences. The left` hand end of.' thefscreW shaft is journalledin a` bracketll.V vand a'rspring Washer 45.V is inserted between A the end of thel threaded portion andther face ofthe bracket 44.` `'llh'esc'rew shaft rotates inbra'ckets 37 ,and 44,' the portionl ofthe 'Worm shaft being freely rotatable relative to the sleeve 36 into which it projects. [The rol.v

' tation of thescrevv shaft is, however, opposedV y by frictionl Washery 45 and friction plate 42.j *A

AThe frictional'resistance ofthe washerand Vplate may be adjusted by rotating the screw 39'Which effects movement of the sleeve .andthe plate 42`abuttin'gthe flange 41` of the sleeve` thereby adjusting the frictional resistance olf-Washer 45 and plate 42 to the roloe tation of the screw shaft. The/positive rotation of the screw by means of rack 30 and pinion 29 is thereby permitted while the tendency Vof the Worm to creep is prevented by the frictional means 45 and 42;

f It is obvious thatf plate 42 Vmay 'be formed j rigidly With flange 4l of the sleeve 36.

l/Vhile I have shown and described and pointed outthe-fundamental novel features of the invention as applied to a single modification it Will be understood thatrvarious" omissions and substitutions and changesin.'

the form and details of the device illustrated and in its operation may'ibe'made byl those skilled in the art Without departing from the spirit' ofthe invention( I intendjto be limited therefore only by the scope of the following claims. 1V

I claims: o l l.v In a meat'slicer, a Wormfor advancing the meat plate, bearing supports for each end j ofthe worm, a friction member coacting with one end ofthe Worm, a spring *WasherV acting on a vertical faceat the other end ofthe Worm urging the Worni'into -frictional contact with said member, said Washer being held 'between Y the latter vertical face and the adj acentsupport, and means threaded into the other support and engaging said disk for adjusting the i frictional force betweenthe disk and 'the' ad-l jacent end o'f the Worm. Y

2. In a meat slicer', a Worm .forV advancing the meat plate,"siipport's for each end 'ofthe Y Worm, .a friction member coacting with one end of the Worm., and a vscrevvrthreaded Yinto the supportfor the latter end of the Worm and having a portion engaging said member to adjus'tthe friction thereoflagainstfthe lat-i' Y ter end ofthe Worm.

, 3.@In a vmeat slicei, a Worin for advancing the meat plate, supports for both ends ofthe i Worm, a spring Washer between onesur'ipvfoit,V and a -fl'at vertical portionV of the adjacent end of the Worm urging thevvorm in' one direc-y tion, a friction disk cooperating Witha verti-V calfac'e on the other end of the Worm, sfegl- -V mentalportions on both the disk a'ndtlieadjacent end'of theY Worm for non-rotatablyYV connecting the tWo5'a flanged collar having Y the'face of the flanged portion engaged Withl the disk and the circularportion rotatably en-l 1 gaging the interiorof the adjacent support;

a sleevewithin the latter support'having one? tend engaging said circular portion, a screw threaded into` theY latter V support and.: nonrotatably keyed t0 the sleeve whereby adjustment of the screw actuates said sleeve to adjust the friction between the disk atti the, fac@ of-thefianged portion of'tliecollar. f-v
